Efficiency of Resource Allocation for Enhanced Quality of Service in MobileWiMAX Networks
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 7
Abstract
The mobile wireless networks have to enable full mobility for users with non degraded Quality of Service (QoS). The QoS is closely related to a mobilityof users. Resource allocation is a vital component of call-admission control that determines the amount of resource to assign to new and handoff connections for quality-of-service (QoS) satisfaction. In this paper, we present approximate analytical formulations of virtual partitioning resourceallocation schemes for handling multiclass services with guard channels in a cellular system. Resource-allocation models for best effort and guarantee access with preemption for best effort traffic and virtual partition with preemption for all classes are investigated. The analytical models, derived using a -dimensional Markov chain, are solved using preemption rules for these schemes. Call-level grade of service, such as new-call-blocking probability, handoff-call-blocking probability, and system utilization, and packet-level QoS, such as packet-loss probability, are used as performance metrics.
